Based on a few conversations I've had with people and some ideas rolling around in my head, I've developed a few thoughts on how I think teams will be split between the two venues. All venue assumptions are just that: assumptions. I may or may not be right.
#1 (District System): Any team that qualifies through the district system will be zoned based on the location of said district. For example, Peachtree would go to Houston, and New England would go to Detroit.
#2 (Regional System): The championship which you qualify for is based on the event location that you originally qualify at. For example, let's say a team from Arizona attends the Northern Lights Regional in Minnesota. If that team won the event, and had not prequalified, they would receive a bid to attend Detroit. If another Arizona team went to AZ North and qualified, then they would attend Houston. However, if the team that went to Northern Lights ALSO went to AZ and qualified, they would still be going to Detroit, not Houston. The team that earned the subsequent wildcard would go to Houston.
#3 (Prequalified teams): All prequalified teams will be assigned based on registered team location in TIMS. This is done far enough in advance and is a small enough number of teams that it shouldn't affect too much.
#4 (District teams competing at Regionals): This is the only major change I think they would have to make. Since FIRST is trying to provide incentive for regions to go to the district model, I believe they would have to choose this solution - if a team from a district attends a regional and qualifies at that event before qualifying any other way, then they DO NOT count into that district's allocation, and, for the purposes of assigning teams to Houston/Detroit, would become a team under point #2. Again, that team would NOT count toward that district's allocation.
This system would, I think, keep the number of teams attending each Championship reasonably constant and predictable.
Just a few thoughts and educated guesses, nothing more.
